What's DARPA, you ask? The Defense Advanced Projects Research Agency, people who invent new technologies to help defend the United States. They invented the Internet, among other things. It's a building full of dedicated people working hard to protect our country. You have to have a reason to visit this building, so don't drop in for a snack, but I'm sure that this cafe is a big help for the people who work there.
I have visited DARPA's new building before, but I hadn't noticed their cafe. This trip offered an opportunity for a quick peek. By the time I arrived at 2 PM, the grill was closed, but they offer a variety of burgers and sandwiches. They also have several refrigerator cases and a wide variety of snacks.
